In this section you will learn and build simple electronic circuits projects. You will make interesting analog electronic circuits useful in daily life. Moreover, you will know electronic circuit design using circuit elements.
The circuits include home made electronic circuits, hobbyist circuits and prototypes.
This article is about building a little hydrophone that can be used to record underwater sounds. Professional hydrophones used in science world are relatively costly, and even do it yourself ideas feature expensive components. As […]
Let’s make a quick and dirty foam cutter! Foam is an easy and cheap material for various prototype creations, and cutting the common polystyrene/Styrofoam is easy with a hot wire cutter. Now do it yourself […]
A fan failure in today’s advanced electronic projects may result in other delicate and expensive components failing, causing costly repairs and delays. A 3-wire PC fan is an easy and inexpensive way to prevent such […]
Having spent a few days messing on with building simple inductive proximity sensor circuits, I’m putting together anew inductive proximity detector device for a small-scale industry. I already have an expandable idea with the sensor […]
If you build battery/usb powered electronics projects, often you’ll be in need of a high-voltage power supply. That is a power supply that has an output voltage higher than that catered by the battery. One […]
In this article, I’ll dig into everything you need to know when it comes to the build of your own minuscule wired/wireless spy camera system. Since the spy camera itself is one of the most […]
Here’s a simple and clever way to build a toggle switch with a quite popular, highly available, and cheap CMOS logic chip CD4049UB. Since the little electronic toggle switch presented here is an easy to […]
Aware that a particular circuit is needed to measure electrical conductivity (EC) of a liquid. Since the conduction of current through a water solution is mainly dependent on the concentration of dissolved ionic substances such […]
Not long ago, we published an article related to this topic. This time the prime aim of this revised article is to serve as inspiration for electronics hobbyists who are making projects which involve driving […]
What should you do when you hear a midnight door knock? Although there’s no quick answer to this question, you must keep in mind that you and your locked door may be the only obstruction […]
